Vertical tabs and workspaces, for people with forty tabs open.

Acira can keep your tabs in a sidebar or along the top, sort them into workspaces and groups, and bring back what you close. It works the way you do when one window has to hold a lot.

Beta for Windows, Mac and Linux

Keep it organized

  • Tabs in a sidebar or along the top. Choose in Settings › Appearance › Layout. Favorites sit at the top of the sidebar.
  • Workspaces. Up to eight per profile, each with its own tabs, groups and splits.
  • Tab groups and pins, for what you want to keep close.

Find and look

  • Command search. Ctrl+Shift+K finds a tab in any workspace or runs a command.
  • All tabs at once. Alt+T shows every tab you have open.
  • Split view, with up to four panes.
  • Link previews. Alt-click a link to look without leaving your page.

Stay light, lose nothing

  • Tab sleep. In our test on one PC, 30 tabs went from 2,693 MB to 859 MB.
  • Rewind. Closed tabs and windows stay for up to a week, and your session comes back after a crash or restart.

Questions

Does Acira have vertical tabs?

Yes. Turn them on in Settings › Appearance › Layout by choosing In a sidebar. Tabs along the top are the default.

How many workspaces can I have?

Up to eight per profile. Tabs, pinned tabs, groups and splits belong to a workspace, while sign-ins, history and bookmarks belong to the profile.

Can I get back a window I closed?

Yes. Rewind keeps closed tabs and windows for up to seven days, searchable, on this computer. Private and Tor windows are never saved.
